How to make rzr run cooler Videos

Backfiring USUALLY happens when unburnt fuel exhausts from the engine, and is ignited back down the exhaust pipe (backfire). Backfiring is USUALLY a result of incorrect engine timing. What happens is sense the timing is slightly off, the exhaust is released early and then ignited upon exit, making the explosion more audible than if it were contained in the cylinder. Incorrect engine timing would seem unlikely for that new of a machine if untouched, however, that specific model of Polaris rzr has a known defect with faulty camshaft lobes, in which most cases, wear down excessively and prematurely, causing the valves to be actuated at the wrong times, so it's not really a timing issue, it's an issue with your camshaft lobes, which this is one of the common complaints of customers affected by this defective part. Only on some engines does it do this, even though they are the same model engines, only a few do this, just because Polaris used that specific camshaft for a certain amount of production time. You should defiantly try to see if your warranty covers this, if not, it is a very costly repair, so I would check with someone of higher knowledge first. Good luck. zc

Quick question for anybody that knows....How often are the dies used in a tap and die set, in the atv/utv/lawn equipment repair world? I know taps are used often, but does a repairman ever even use dies? Just answer me directly so theres not a long discussion under this video. Thanks a lot y'all.
